Description

[0001] The invention relates to the technical field of motor control, in particular to a motor. Background Art

[0002] With the advancement of science and technology and the development of the times, more and more motors are used in our production and life; among them, the traditional motors that are widely used are mainly copper-core winding motors, which have strong output power and high power conversion efficiency, and are very suitable for use as drive units.

[0003] However, since traditional motors require windings to be wound around the iron core, there are certain limitations when making changes to the windings. For example, when doubling the power, not only the size and specifications of the windings need to be changed, but also the relevant design parameters of the iron core and the rotor need to be changed, which leads to the need to redesign the entire motor and replace the windings. It is also more troublesome, and only motors of suitable specifications can be replaced to meet usage requirements. This means that warehouses need to stock many specifications of motors for emergencies. If there is no stock, they need to be re-purchased, which increases the stocking cost, the number of purchases and delays in work.

[0056] Embodiment 1

[0057] Please refer to Figure 1 , this embodiment of the application provides a motor, including a plurality of motor rotor layers 1, a plurality of motor stator layers 2, a plurality of motor rotating shaft layers 3, a motor rotating shaft head 4, a motor rotating shaft tail 5, a motor housing, a control unit and a power supply unit; among them,

[0058] The motor stator layer 2 is arranged through an integrally formed conductive layer, and a shaft hole is penetrated and opened at the central axis position;

[0059] Each of the motor rotor layers 1 and the motor stator layer 2 is arranged in an alternating structure, and a rotation gap is left between each layer; among them, the uppermost layer and the lowermost layer of the alternating structure are both set as the motor rotor layer 1 or the motor stator layer 2;

[0060] On one side of the motor rotor layer 1 close to the adjacent motor stator layer 2, a number of magnets with alternating N and S poles are arranged uniformly around the central axis;

[0061] The middle position of the motor shaft layer 3 is fixedly connected to the central axis position of the corresponding motor rotor layer 1, and the upper part and / or lower part of the motor shaft layer 3 pass through the shaft holes of the corresponding adjacent motor stator layer 2;

[0062] Each of the motor shaft layers 3 is fixedly connected end to end in sequence, and the top of the uppermost motor shaft layer 3 is fixedly connected to the motor shaft head 4, and the bottom of the lowermost motor shaft layer 3 is fixedly connected to the motor shaft tail 5;

[0063] The motor housing seals the interiors of each motor rotor layer 1, motor stator layer 2, motor shaft layer 3, and motor shaft tail 5, and exposes the outside of the top of the motor shaft head 4;

[0064] The control unit is electrically connected to the host computer and the power supply unit respectively, and the power supply unit is electrically connected to each motor stator layer (2); among them,

[0065] The control unit is set and runs a motor control program through an MCU control chip; among them, the control unit receives a host computer control signal, and according to the host computer control signal through the motor control program, it is converted into a corresponding motor drive signal and sent to the power supply unit.

[0066] The power supply unit is set through a three-phase power supply management chip; among them, the input end of the three-phase power supply management chip is connected to the power input, the output ends are electrically connected to the phase A power opening 16, phase B power opening 17, and phase C power opening 18 respectively, and the control end is electrically connected to the control unit and receives the motor drive signal, and converts the power input into a corresponding motor three-phase output.

[0067] It should be noted that: Traditional motors require windings to be wound around iron cores. After the motor is encapsulated, there are certain limitations when making changes to the windings. For example, when doubling the power, not only the size and specifications of the windings need to be changed, but also the relevant design parameters of the iron core need to be changed, which leads to the need to redesign the entire motor and it is also more troublesome to replace the windings. In actual use, we are required to select a motor with a suitable output specification according to the usage scenario; therefore, we need to prepare many specifications of motors for emergencies. If there is no stock, we need to re-purchase, which increases the stock cost, the number of purchases, and the problem of delaying work.

[0068] To this end, this embodiment designs the motor structure through a multi-layer reconfigurable architecture, and sets the motor stator layer 2 through an integrally formed conductive layer, thereby two-dimensionalizing the traditional winding, and providing a basis for layered stacking; further, we set the motor rotor layer 1 and the motor stator layer 2 in an alternating structure, and leave a rotation gap between the layers. We can choose the number of stacked layers and the setting order of the alternating structure side according to needs, and only need to keep the topmost layer and the bottommost layer of the alternating structure set as the motor rotor layer 1 or the motor stator layer 2 at the same time; the motor shaft is also designed with a multi-layer reconfigurable architecture, and the motor shaft length is configured according to needs through a number of motor shaft layers 3, motor shaft heads 4, and motor shaft tails 5.

[0069] The motor provided in this embodiment, when faced with the demand for exponentially increased power, only needs to change the number of layers of the multi-layer reconfigurable architecture according to the corresponding power ratio to complete the task, without the need to redesign and manufacture the entire motor, and does not involve improvements and reorganization of the core and windings; therefore, the workload is greatly reduced.

[0070] in, Figure 1 Schematic diagram of a multi-layer reconfigurable architecture in which the top and bottom layers are both set as the motor rotor layer 1. Since the top and bottom motor rotor layers 1 only have a single layer corresponding to the motor stator layer 2; therefore, the following is adopted: Figure 10 The single-side motor rotor layer 11 is set as shown, and the remaining motor rotor layers 1 are arranged as shown in FIG. Figure 9 The double-sided motor rotor layers shown are set up.

[0071] Specifically, Figure 3 As shown, in order to realize that the motor housing can be flexibly configured according to actual conditions, we also adopt a multi-layer reconfigurable architecture to design the motor housing, including a motor top cover 81, a motor bottom cover 83 and a motor annular shell 82; wherein,

[0072] Annular positioning grooves are provided at the upper and lower edges of the motor stator layer 2, and the annular positioning grooves are larger than the outer edge of the motor rotor layer 1;

[0073] When in use, we only need to set the motor annular shell 82 between adjacent motor stator layers 2, and then limit and fix it through the annular positioning groove, so as to form a sealed space between the motor stator layers 2, and the motor rotor layer 1 between the adjacent motor stator layers 2 can be sealed inside through the sealed space, so as to achieve layer-by-layer stacking and adaptation;

[0074] Finally, if Figure 4 As shown, the motor top cover 81 is then fixed by the annular positioning groove on the upper side of the uppermost layer, as shown in FIG. Figure 6As shown, the motor bottom cover 83 is limited and fixed through the annular positioning groove on the lower side of the lowermost layer, and the adaptation and encapsulation of the entire motor structure can be realized.

[0075] In addition, due to the presence of the motor top cover 81 and the motor bottom cover 83, only the motor rotating shaft layer 3, the motor rotating shaft head 4, and the motor rotating shaft tail 5 need to be fixedly connected through nuts and bolts, male and female splines, or pin slots to achieve axial fixation and lateral limitation.

[0076] When the motor is working, to ensure the overall stability of the multi-layer reconfigurable architecture, as Figure 3 and Figure 4 shown, we also set a top chamber 9 on the motor top cover 81; as Figure 5 and Figure 6 shown, a bottom chamber 10 is also set under the motor bottom cover 83. An upper roller 6 is arranged in the top chamber 9, and a lower roller 7 is arranged in the bottom chamber 10;

[0077] Specifically, as Figure 7 shown, the motor rotating shaft head 4 passes through the top chamber 9 and is rollingly linked with the motor top cover 81 through the upper roller 6; as Figure 8 shown, the motor rotating shaft tail 5 is placed in the bottom chamber 10 and is rollingly linked with the motor bottom cover 83 through the lower roller 7; the upper roller 6 and the lower roller 7 can reduce the friction and impact generated during the operation of the motor.

[0078] However, since the motor rotating shaft is composed of multiple layers of structures, some gaps are inevitably generated during assembly; therefore, as Figure 8 shown, we also set a spring gasket 21 at the bottom of the bottom chamber 10. The bottom end of the motor rotating shaft tail 5 is placed at the bottom of the bottom chamber 10 through the spring gasket 21. The spring gasket 21 can push the motor rotating shaft to be pressed tightly, thereby reducing the gaps between the layers and improving the overall stability of the rotating shaft.

[0079] As Figure 11 shown, the integrally formed conductive layer is formed by setting isolation gaps 20 in a whole conductive sheet, and several phase electrical interfaces are set; among them, the isolation gaps 20 divide the whole conductive sheet into several phase electrical blocks, and the phase electrical blocks are respectively electrically connected to the corresponding phase electrical interfaces. As Figure 5 shown, the phase electrical interfaces are led out through electrical openings 12.

[0080] It should be noted that: The traditional PCB motor simulates the motor winding through the PCB circuit board to achieve axial volume compression of the motor winding. However, in order to save costs, reduce processing time and process flow, the PCB circuit usually adopts an etching processing technology to form an extremely thin layer of conductive circuit on the circuit board. Therefore, it cannot withstand large current voltages, which results in limited output power and difficulty in enhancing it, unable to meet the requirements of output power.

[0081] Specifically, the unit of copper thickness of the PCB board is generally ounce (oz), 1 oz = 0.035 mm. Generally, the single-layer copper thickness is below 6 oz, and in special occasions, it will reach above 6 oz. The copper thickness is related to factors such as current-carrying capacity and line width. The PCB stator requires a large current-carrying capacity. Compared with electronic circuits, the current is very large. With a certain wire width, a thicker copper thickness is required, which belongs to a thick copper board. However, if it is too thick, the PCB manufacturer may not be able to produce it. Even if it can be produced, thick copper has high requirements for the accuracy and technology of the machine, so the cost is very high.

[0082] To solve the problem that the PCB motor cannot withstand large current voltages, this embodiment adopts an integrally formed conductive layer. The integrally formed conductive layer is mainly a whole conductive sheet, and the conductive sheet can be a copper plate, an aluminum plate or other conductive materials. We use methods such as laser engraving, organic processing, stamping processing, or die-casting cutting to set isolation gaps 20 in the whole conductive sheet. We can fill insulating materials, soft magnetic materials, etc. in the isolation gaps 20 to form conductive circuits. In this way, a thicker and more complete conductive circuit can be obtained, which has the advantages of higher structural strength, better electrical conductivity and magnetic permeability, and stronger pressure-bearing capacity compared with the PCB circuit, and the processing difficulty and accuracy requirements are low, and most processing manufacturers can complete the processing tasks.

[0083] In addition, the rotor can also generate magnetic poles in a similar way to the stator winding, such as replacing the magnet through a conductive sheet (coil), that is, inducing N / S magnetic poles through the conductive sheet (coil), and driving in the form of self-excitation or separate excitation, so as to realize the overall electric drive of the motor.

[0084] Furthermore, the phase electric block area includes alternately arranged A-phase electric block areas 13, B-phase electric block areas 14, and C-phase electric block areas 15. The phase electric interfaces are provided with A-phase electric interfaces, B-phase electric interfaces, and C-phase electric interfaces. The electric openings 12 are provided with A-phase electric openings 16, B-phase electric openings 17, and C-phase electric openings 18.

[0085] Embodiment 2

[0086] Please refer to Figure 12, after completing the structural reorganization of the motor, it is also necessary to update the motor control program to adapt to the reconfigured motor; for this purpose, based on Embodiment 1, this embodiment provides a control method for the motor, including the following steps:

[0087] Step 1: Determine the alternating structure used by the motor and assemble the motor; among them, it includes the types of the uppermost layer and the lowermost layer and the number of layers used in the alternating structure;

[0088] Step 2: Update the parameters of the motor control program according to the alternating structure; among them, it includes control parameter update, conversion parameter update, and control instruction update;

[0089] Step 3: Save the updated control instructions and control parameters to the host computer, and the host computer generates a host computer control signal through the updated control instructions and control parameters;

[0090] Step 4: The control unit receives the updated host computer control signal and converts the host computer control signal into a corresponding motor drive signal according to the updated conversion parameters;

[0091] Step 5: The control unit sends the motor drive signal to the power supply unit, and the power supply unit receives the motor drive signal and converts the power input into a corresponding three-phase motor output;

[0092] Step 6: The power supply unit inputs the three-phase motor outputs into the motor stator layer 2 of the alternating structure respectively, and generates a corresponding electromagnetic field through the integrally formed conductive layer;

[0093] Step 7: Each motor rotor layer 1 is driven by the electromagnetic field, rotates around the central axis, and transmits the driving force to the motor shaft head 4 through the motor shaft layer 3.

[0094] Through the above steps, we can realize the full-process update and reconstruction from the motor to the control unit and then to the host computer, and can very conveniently increase or decrease the output power by multiples to adapt to different application scenarios, without the need to prepare motor devices and drive units of different specifications, and is very suitable for use in complex and changeable scenarios.

[0095] The above are only some embodiments of this application, and do not limit the patent scope of this application accordingly. All equivalent structural transformations made under the technical concept of this application by using the content of the specification and drawings of this application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of this application.
